.To LU whom, t muy concern.'

Be it known that l, SMITH KEiGHLEY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in F ireproof Metal VVindoW Frames and Sashes; and l do declare the following to be a full, clear, and ex- 'act descriptionof the invention, such as Will enable others skilled in the art to whiclrit appertains to make and use the same.

This invention relates to sheet-metal fireproof windows; andv one of the principal objects of the same is to provide means for re duclng the friction between the sash and the window-frame and at the same time to provide means for excluding wind, snow, rain, or ice from between the sash and frame.

Another ob'ect of the Iinvention is to provide improve means for adjusting the pulley-Stiles of the window-frame to conform to the dimensions of the sash and to compensate for variations between the Window frame and sash, to insure smooth operation of the parts, and to prevent the binding of one part upon another.

Another object is to provide in asheetmetal fireproof window a sash-guide to accommodate a weather-strip u on a sash and to permit the free and smoot 1action of the strip within the guide Without creating undue friction and at the same time to prevent rattling of the parts.

The foregoing and other objects are accomplished by means of the construction illustrated in the accompanying drawings, in Which Figure l is a horizontal section taken through the side of a window-frame, the adjustable pulley-stiles, and one section of the sash of a metal fireproof window made in accordance with my invention. Fig. 2 is a perspective view of a short section of a sash with a guide-strip formed thereon in accordance with my invention. Fig. 3 is a horizontal sectional view taken through one of the screws for adjusting the pulley-stiles and showing a portion of the window-casin and the pulley-stile.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates a sheet-metal fireproof window-casing having a rectangular portion 2, designed to accommodate Weights t 71y for operating sash and which fits a recess 3 in the wall of the building and extending thence outwardly to form shoulders 3', fitted against the inner surface of the wall. -Thecasing is formed into a molding 4,'at the outer side thereof, and the edge of the sheet metal extending thenee inwardly at' .5, baclnvardly at (i, and outwardly at 7, a slight projection 8 being formed at a point to extend from bot toni to top of the sash and to bear against the weather-strip and prevent the passage of air or the accumulation of rain, snow, or ice at this point. At the inner side of the casing the terminal 9X of the metal is plain, and the projection 8 may be omitted from this portion of the casing. The pulley-stiles 10 may be formed of two separate portions or strips, each consisting of a strip bent to form a groove l1 for the terminal edge 9 of the casing and extending thence to form a facing for thc window-frame and then bent inwardly to form a guide 12 for the weather-strip upon the sash. The terminal edge of the sashguide strip is secured to a division-strip 13, said strip extending outward to form separate sash-weight pockets 14 15, the. metal boing bent inwardly to forni two points (L I), hetween which the weather-strip is adapted to slide and to be guided by said oints without undue friction of the parts. `rom the portion a the strip extends across to form the other sash-guide and is bent at c in a manner similar to the bend d,and the sash-guide thence being formed into a groove or pocket for the terminal end of the front portion of the window-casing and thence extending outwardly' to 'form a terminal flange 16. ln order to adjust the pulley-Stiles to compensate for sashes of slightl yvarying wid ths, a series of threaded bolts 17 pass through the face portion of the window-casing at opposite sides of the 'sashgrooves, said bolts extending through the terminal flanges formed on thepulley-stiles and through nuts lying against and preferably secured to said flanges, said nuts being provided with an extension 1S, which extends back of the pulley-stile and connects with the nut on the opposite side, Aforming a continuous reinforcement which holds the pulley-stile stiff and rigid and which fits across the grooves or pockets.

The window-sash coin rises a hollow sheetmctal oppositely-forme molding 19, intermediate grooves 20 for the glass, and the two side walls or surfaces 21 22, the wall 22 extending backward and bent upon itself, as at 23, to form a weather-strip adapted to 'lit and move freely in the sash-guides. A cross- IOO strcilp 24 is bent into substantially U shape, an one limb of the U extends between t'wo portions 'of the wall 21 and is secured therein by means of rivets 25. The opposite side of this cross-strip is similarly bent, and the side wall 22 is bent around the terminal edge of the cross-strip and secured by rivetsl in a manner similar to the opposite side, thus forming a projecting guide e to bear against the inner surface of the facing strip or pulleystile to insure a true and smooth action of the sash, while the .projection f forming the weather-strip fits one of the guides and moves freely therein.

From the foregoing it will be obvious that a sash and window casing made of metal in the form shown and described will move freely and regularly without binding and withouJ creating undue friction against the frame and that the parts will be comparatively close between the weather-strip and the window-casing to exclude the elements and that the facing-strips or pulley-Stiles may be adjusted for compensating for any variation in the sash with the view of insurin a smooth action and removing the liabiIity of the binding of the various parts.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a metal weather-strip and sash-guide, a metal strip having oppositelydisposed bearing-points extending toward each other, in combination with a metal sash having an extended weather-strip adapted to move between said bearing-points7 substantially as described.

2. In a metal fireproof window, a hollowmetal window-casing, pulley-Stiles secured thereto, sash-guides formed in said stiles and provided with two oppositely-disposed bearing-points 8, c, in combination with a metal window-sash having one of its walls bent upon itself and inclosing a cross-strip to form a weather-strip f to move betweenV said bearbear against the facing of said pulley-stile,

substantially as described.

4. A metal window-sash having its terminal inner edges bent to form a weather-strip f and a guide-flange e and inclosing a crossstrip 24, said parts beiner riveted together, in combination with ameta Window-casing having a sash uide or chamber into which the weather-strlp iits and slides, substantially as described.

. 5. In a metal window, the combination of j pulley-Stiles provided with terminal flanges 9X, 16, va window-casing7 bolts passing through said casing and through said flanges for adjusting the pu-lle -stiles to compensate for the variation in t e size' of sash, sashguides formed in said stiles and provided with oppositely-disposed bearing-points 8, c, and a sash having a projecting weather-strip f to fit between the oppositely-disposed bearing-points and move 1n the sash-guide7 substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

SMITII KEIGHLEY.
